The invention relates to a data transmission technology, known as faster-than-Nyquist (FTN) signaling. When data pulses are transmitted at FTN signaling rate, inter-symbol interference (ISI) must be removed at the receiver using a detector to prevent an increase in bit errors. This allows for increasing the number of transmit bits within the same bandwidth and using the same transmission power of conventional Nyquist signaling. The inventors developed a FTN signaling detector for ultra-high-order quadrature-amplitude modulation (QAM). Simulation results show that this detector achieves excellent performance for ISI removal and reconstruction of the transmitted data symbols, at a very low computational effort, compared to the existing detectors.
